To all-whom it may concern:

Be it known that 1, JAMES E. ORR, a citizen of the United States, residing atDallas, inthe-county of Dallas and State ofTeXas, have invented certain new and useful Improvements in VVindow-Shade Guides, of whichthe following is a specification.

This invention relates to new and usefulimprovements in guides for window shade rollers.

It is practically impossible to hang a window-shade roller so that the shade will wind and unwind without creeping toward one end of the roller and engaging the supporting bracket. If the roller is hung exactly level the settling of the buildlng or the swelling of the wood in damp weather will displace it. Many persons catch hold of a shade at one side to raise or lower it. The frequent contact of the edges of the shade of the brackets soon wears and tears the shade so that it must be replaced or is very unsightly.

My invention contemplates a simple attachment which may be applied to each end of the roller whereby the latter is converted into a spool and the shade smoothly and evenly wound and unwound without injury.

is revolved.

In carrying out the invention a collar is formed and provided with means for fastening it on the end of a roller in close relation to the end of the shade wound on'said roller. The collar is provided with a convex face next to the end of the shade which acts to guide the shade into position as the roller The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawings, in which an example of the invention is shown and wherein:

Figure 1 is a view of a roller equipped with guides made in accordance with this invention, the shade being shown in section,

In the drawings the numeral 1 designates an annular concavo-convex collar having a v the roller.

convex face 2 and provided with a central circular opening 3 large enough to receive the end of a window shade roller A.

In Figs. 1, 2 and 3 the collar has an outwardly bentlug 4 at its opening and on the concaved'or rear side. The lug carries a set screw 5 which hasits inner end battered to prevent displacement from the lug when not in use. The collar is slipped on the end of the roller A so that its convex face 2 is in juxtaposition to end of the shade B wound on the roller. By tightening the screw against the roller the collar is fastened in place.

The collars are fastened on each end .of the roller as is shown in Fig. l and when the roller is revolved to wind or unwind the shade the convex faces 2 will guide the shade to a central position if said shade tends to wind or unwind toward either end. The faces 2 flare outward and thus do not interfere with the operation of the shade but if engaged by the edges of said shade, act to displace said edges inward flush with the ends of the roll of shade on the roller. The lug is bent out enough to permit the inner battered end of the screw to clear the roller as the collar is slipped on or off of the said roller.

It is obvious that various means for fastening the collar on the roller could be evolved and I have worked those forms which I consider most practical,

In Figs. 4 and 5 I have shown a collar in which the central opening 3 is surrounded by a plurality of inwardly directed radial teeth 6 having their points bent slightly rearward and terminating in a circle of slightly less diameter than that of the roller on which the collar is placed. The rearwardly bent points permit the collar to be easily slipped onto the. roller, but any tendency toward displacing the collar outward or rearward causes the points to bite into In Figs. 6 and 7 the collar has an outwardly bent clamping ring 7 surrounding the opening 3 and having its ends 8 cut free from the collar and provided with ears 9 receiving a screw 10 by which the ears may be drawn together and the free ends 8 clamped about the roller.

' In Figs. 8 and 9 a slightly tapered and externally threaded split sleeve 12 is mounted on the end of the roller with its reduced end toward the end of the roller. The collar has the surrounding edges of its opening 3 provided with screw threads 11. As the collar is screwed onto the sleeve the latter is contracted and binds on the roller as is obvious.

It will be seen that all of these structures are readily fastened on the roller without altering or changing the roller and may be expeditiously applied by an unskilled per son.

What I claim, is:

1. In a window shade guide, in combination with ashade roller and a shade adapted to be rolled thereon, a pair of guidemembers mounted on opposite ends of the roller and having inner opposed convexed faces adapted to receive and guide therebetween T the successive layers of the shade as the latter is wound upon the roller.

2. In a windowshade guide, in combination with a shade roller and a shade adapted to be wound thereon, a guide member mounted on the end of the roller and having a convexed'guiding face adapted to receive thereagainst the adjacent vedge of the shade and guide the successive layers thereof into a uniforrnroll during the winding of the shade on the roller.

3. A window shade guide provided with means for securing the same on the end of a shade roller and having a convexed face adapted to guide the edge of a shade during the Winding of the same into successive layers onthe roller. i

In testimony whereof I aflix my signature.
